🐛 Notification panel flashes doubled state

[petertgiles]

🐛 Bug

When the notification panel is opened it flickers through an intermittent state. It appears that maybe it's showing double notifications before deduplicating them?

🦋 Expected Behaviour

It makes sense to show an old state then suddenly change to a new state but the middle state that represents neither is disorienting.

🕵️ Details

📋 Steps to Reproduce

1. Confirm you have more than one notification in the panel.
2. Generate a file and wait a few seconds so that it is ready.
3. Open the notification panel and watch how it changes before settling.
